CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 379,430, dated March13, 1888.

Application filed August 22, 1887. Serial No. 247,555. (No model.)

To all whom t may concern,.-

Be it known that I, CURTIS WHITEHALL, of Mellott, in the county ofFountain, State of Indiana, have invented certain new and usefulImprovements in Cultivators; and I do hereby declare the following to'bea clear and exact description ofthe same.

This invention relates to that class of strad-v dlerow cultivators inwhich the operator walks and guides the plows, which are arranged ingangs, so as to cultivate both sides ofa row of plants at the same time.

My invention consists, chiefly, of a peculiar construction by which Iobtain compound endless plow-beams having swinging lateral motion ontheir fastenings or pivots, obtaining simplicity, greater strength, andincreased faoilily in working. I attain these objects by the mechanismshown in the accompanying perspective view of my cultivator.

A A represent the wheels, and B B the axles. The saddle or arch C ispreferably solid with the axles, the whole being formed of a continuousbar, shaped as shown.

D D show supports for the rear ends, a, of the tongue E, said ends beingloosely secured about midway of their length to the arch or saddle C bystaples a', so asY to be vertically adjustable.

F is an ordinary yoke extending across and pivoted to the tongue E andloosely held by adjustable links b and couplings 'c to the struts dsecured to the axles and arch, as indicated.

At the top of the saddle C is aspring-hanger, G, to the ends ot' whichare suspended, so as to be vertically adj ustable,the hooks e. Sleevesor sockets j' surround the horizontal partsf of the arch, said sleevesor sockets being connected to back plates, g. From the back beams H is aplate, 7c, in which the endless bars t' composing the compound beams arejournaled and to which plate the shovels I are attached. The handles arerepresented by J, a handle being attached to each compound beam.

It will be seen that the compound beams have a lateral mog/ement in theback plates, g, and that the two endless bars z' of the beams H, byreason of their being journaled at each end, constantly maintain thesame distance apart.

This construction of beam gives to it great strength and permit-s of theadjustment of the plows Withgreat facility. The hooks e and li and thespringhanger G give a certain elas` ticity to the beams H, the tendencyof the springhanger being to raise the beams. This elasticity can bevaried by the adjustability of the suspensionvhooks e. Irl/'hen theplows are not in use, the beams H are raised and held up by means of thehooks k.

Having described my invention, I claim- In a wheelvcultivator, the archC and compound beams H, hinged thereto and capableoflateraladjustment,combined withthespringhanger G and hooks e h,substantially as set forth.

In testimony whereof I have hereunto set my hand and seal.
